Mayland Long and Martha Macnamara are as unlikely a couple as you could hope to meet. Martha is a fiftyish musician, Mayland is-- well, Mayland is unusual, as people who have read the first book in this set, Tea With the Black Dragon, know. When the book opens Mayland, Martha, Martha's young granddaughter Marty, and an ill assorted group of egotistical musicians have been on tour for eight weeks, playing traditional (and not so traditional) Irish folk songs. At this point tempers are frayed while insults (and the occasional fist) are flying.
Then Marty disappears, a member of the band is found hanged by a twisted grass rope off a Pacific pier, and it up to Martha and Mayland to solve the mystery of where Marty is and who the murderer is.
Written in the mid 80's this book is a great favorite of mine, an urban fantasy mystery that mixes Celtic and Eastern lore with some solid detection. The scenes with the band seem very true to life and the fantasy elements are delightfully underplayed. The chapter titles, by the way, as well as the title Twisting the Rope are all titles of trad. Irish tunes.
